v VIOLIN.

-Appneatin inea october 2o, 1925.y seriaiNo. 63,655.

It hask been heretofore proposed to increase the `quality and strength of the tone of ystringed instruments and particularly of the violin by providing a base bar longitudinally of the stringed instrument, the same being vplaced on the under sideoof the top wall in providing a base barhaving disposed 'at .either end thereof, an enlarged sectional area which is adapted to attachment to the under side ofthe top wall surface, and which bridges the space therebetween and it is yadapted to the placement of a movable support between the top wallustructure `and the base bar so as to increase, or decrease, the tension upon the base bar and, therefore, upon the top wall structure as well.

yWith these and incidental objects in view, the invention consists in certain novel 'features of construction and combination of parts, the essential ele-ments of which are set forth in the appended-claims, anda preferred form of embodiment of which is hereinafter shown witlifreference to the drawings which accompany and form a part of rthis specification.

In thek drawings Fig. 1 is an inverted plan view, of my new and improvedviolin, :illustrating myL new and improved basebar, in position, on the under side ofthe top wall surface of the violin.

Fig@ is a longitudinal, cross section view, taken on line 2 2 of Fig. 1, looking in the direction indicated.

Fig. 3 is a cross section View, taken on line 3 3 of Fig. l, looking in the ydirection indicated. y f

Fig. 4 is an inverted perspective view of rthe base bar, illustrating a preferred form of attaching the same to the under side of the top wall of the stringed `instrument and illustrating the tension member as applied thereto. y

- Like reference characters refer to like parts throughout the several views. f 1L isthe body portion of the stringed instrument, having a top wall surface 2, disposed upon. the body portion,the bridge of' the violin being shown at 3, and the bridge post at 4. Disposed longitudinally -of the instrument and on the under side of the top wall surface is the base bar 5, which is positioned beneath one of the strings of the instrument and longitudinally of the inst-rument, and has enlarged end terminals 6 and 7, disposed at either end of the same; base bar 5, is ymade integral therewith. These end terminals 6 and 7, are so made. in contour yand arrangement tobe readily attached to the underside of the top wall surface 2 by glue, or other suitable fastening means. In a preferred embodiment of my 'new and improved violin, the base bar is attached to the underside yof the top Wall surface by means of the end terminals and that. portion of the bar intermediate its ends is spaced apart from the under surface of the top wall 2. Disposed between the end terminals and the base bar 5, is a secondary bar 8, the same being secured to the under side of the top wall of the stringed instrument and in line with the base bar. The secondary bar is directly mounted to the undersnrface of the top wall and in parallel alignment with the base bar and in spaced relationship therewith. The adjacent or op` positely positioned edges of the base bar 5 f3 and the secondary bar 8 are curved longitudinally, but are not of the same degree of curvature, the secondary bar being slightly more curved than the base bar, so that the distance between the two bars varies intermediate their ends. The distance between the bars being the shortest at the longitudinal center points of each of the bars, which center ypoints are spaced opposite each other. The tensioning post 9 has grooved ends which lit over and engage the oppositely facing curved surfaces of the two bars, and as the tension bar is moved along the bars toward the center thereof, the pressure upon the tension bar increases, and it is the change of pressure upon the two bars that modifies or changes the tone of the instrument.v

Experience has shown that the tension placed upon the base bar determines the quality of the tones to be produced upon the stringed instrument and that this quality of tone and the volume may be determined and increased, or diminished, by the change in position of the. tensioning member, which lll) increases7 or decreases, the tension upon the base bar and therefore, upon the top wall of the instrument. Because of the fact that my new and improvedL violin has the base bar with its tensioning member placed: on the inner side of the top wall7 does not in any way detract from the beauty of the instrument. The same may be attached at the time of the manufacture of the instrument, or placed at a later time.

One of the primary objects of my invention is to compensate for the changes in tension of the top wall surface of the stringed instrument caused by changes in temperature, climatic changes and other natural causes. My invention also enables those skilled in such matters to harmonize several instruments to create music of a liner quality and of greater harmony.

TWhile the form of mechanism herein shown and described is admirably aclanted to fullill the objects I niinarily stated, it is to be understood that it is not intended to con* tine the invention to the one form of einbodinient herein shown and described, as it is susceptible of embodiment in various forms7 all coming within the scope of the claims which follow.

that I claim is 1u l. A base bar for aI violin, in combination with the upper wall of a violin, of a base bar secured by its ends to the underside of said wall, and having that portion thereof intermediate its ends spaced apart therefrom, a secondary bar mounted to the under surface of said upper wall and spaced apart from said base bar, and a tension bar slidably positioned between said base bar and said secondary bar.

2. A base bar for a violin, in combination with the upper wall of a violin. of an arched base bar, longitudinally semicircular in cross section mounted to the underside of said upper wall, and having that portion intermediate its ends spaced from said npper wall; a secondary bar mounted to the underside of said top wall and in a vertical plane with said base bar, said secondary bar havin;l an unatlached edge longitudinally semicircular in cross section and spaced between said base bar and top wall; and a grooved tension bar disposed between and slidably engaging said base bar and said secondary bar.
